No. These plans provide data only and do not include calls or texts.

South Korea: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in South Korea means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, and reaches 2 networks — LG Uplus, SKTelecom — so your phone can move to whichever one has signal. Your usual number stays active on the same phone throughout.
